Mood disorders including major depressive disorder and bipolar disorder are common during and after pregnancy. Timely identification and appropriate management of mood episodes is essential to maximize maternal well-being and minimize adverse outcomes. Failure to do so results in maternal suffering and impaired child bonding, and has the potential for devastating outcomes including suicide and infanticide. Women are routinely screened for unipolar depression during or after pregnancy but not for bipolar disorder, in spite of the fact that childbirth is associated with a major risk for onset or exacerbation of bipolar disorder...

Imbalances in the sex ratio at birth in Southeast and East Asia increased especially after the mid-1980s. We study how ultrasonic technology affected sex ratios at birth in South Korea, a country with a strong son preference. Between 1985 and 1995 fetal screenings and abortion services were widely available, though not available in the years before, and prohibited in the years after. Using the 1985, 1995, and 2005 Census microdata, we examine changes in sex ratios of newborns by birth year. We then study periodic effects on the fertility stopping rule, using the 2006 Korean Longitudinal Study of Aging, which provides birth years for all children...

BACKGROUND: Oxidation-specific epitopes (OSEs) are proinflammatory, and elevated levels in plasma predict cardiovascular events. OBJECTIVES: The purpose of this study was to develop novel positron emission tomography (PET) probes to noninvasively image OSE-rich lesions. METHODS: An antigen-binding fragment (Fab) antibody library was constructed from human fetal cord blood. After multiple rounds of screening against malondialdehyde-acetaldehyde (MAA) epitopes, the Fab LA25 containing minimal nontemplated insertions in the CDR3 region was identified and characterized...

BACKGROUND: The major causes of maternal and neonatal mortality in the Philippines are hemorrhages and obstructed labor due to placental implantation abnormalities (PIAs), twin pregnancies and fetal malpresentations. All of which are all easily detected by ultrasound. However, women in rural areas and low-income groups do not have access to ultrasound during their prenatal care. We aimed to provide additional evidence on the benefits of handheld ultrasound (HU) for screening pregnancy related abnormalities in order to avert maternal and neonatal deaths...

Recent studies have established important roles of de novo mutations (DNMs) in autism spectrum disorders (ASDs). Here, we analyze DNMs in 262 ASD probands of Japanese origin and confirm the "de novo paradigm" of ASDs across ethnicities. Based on this consistency, we combine the lists of damaging DNMs in our and published ASD cohorts (total number of trios, 4,244) and perform integrative bioinformatics analyses. Besides replicating the findings of previous studies, our analyses highlight ATP-binding genes and fetal cerebellar/striatal circuits...

BACKGROUND: Fetal ethanol (ETOH) exposure can damage the developing central nervous system and lead to cognitive and behavioral deficits, known as fetal alcohol spectrum disorders (FASD). ETOH exposure to mouse pups during early neonatal development was used as a model of ETOH exposure that overlaps the human third trimester "brain growth spurt" - a model that has been widely used to study FASD in rats. METHODS: C57BL/6 male and female mice were exposed to ETOH (4 g/kg/day) on postnatal days (PD) 4-10 by oral intubation...

BACKGROUND: Regenerative medicine aims to provide therapeutic treatment for disease or injury, and cell-based therapy is a newer therapeutic approach that the conventional medicine cannot do. The ethical issues rose by the utilisation of human embryonic stem cells (hESC) and the limited capacity of adult stem cells, however, hinder the application of these stem cells in regenerative medicine. Recently, isolation and characterisation of c-kit positive cells from human amniotic fluid, which possess intermediate characteristics between hESCs and adult stem cells, provided a new approach towards realising their promise for fetal and adult regenerative medicine...

Two novel series including Schiff bases of the pyrrolizine-5-carboxamides and their Cu(II) complexes were designed, synthesized and analysed using spectral and analytical techniques. The analytical results indicated the formation of the complexes in 1:1 or 1:2 (Metal:Ligand) ratio. The geometry around the Cu centers was confirmed to be tetrahedral or octahedral. The cytotoxic activity of the new compounds was evaluated using MCF-7 (human breast adenocarcinoma), A2780 (human ovary adenocarcinoma) and HT29 (human colon adenocarcinoma), in addition to MRC5 (normal human fetal lung fibroblast) cells using the MTT cytotoxicity assay...

OBJECTIVE: We present a comprehensive systematic review of published literature to examine, whether arterial stiffness and wave reflection measurements during pregnancy differed between healthy patients and patients with placental-mediated diseases including preeclampsia (PET), small for gestational age (SGA), fetal death, and placental abruption, and a quantitative assessment of the findings using the meta-analysis approach. METHODS: We searched Medline, Embase, and The Cochrane Library for studies of arterial stiffness in pregnancy, analyzed pregnancy outcomes and conducted the meta-analysis of data evaluated by trimesters of pregnancy...

BACKGROUND: Mutations in the NCF1 gene that encodes p47phox, a subunit of the NADPH oxidase complex, cause chronic granulomatous disease (CGD). In Kavkazi Jews, a c.579G>A (p.Trp193Ter) mutation in NCF1 is frequently found, leading to CGD. The same mutation is found in about 1% of Ashkenazi Jews, although Ashkenazi CGD patients with this mutation have never been described. METHODS: We used Sanger sequencing, multiplex ligation-dependent probe amplification (MLPA), gene scan analysis and Ion Torrent Next Generation Sequencing for genetic analysis, and measured NADPH oxidase activity and p47phox expression...

Human cytomegalovirus (HCMV) infection is the primary viral cause of congenital abnormalities and mental retardation in newborns. The HCMV UL141‑encoded glycoprotein has been previously revealed to inhibit the cell‑surface expression of cluster of differentiation (CD)155, CD122, tumor necrosis factor‑related apoptosis‑inducing ligand death (TRAIL)‑receptor 1 (R1) and TRAIL‑receptor 2 (R2), thus protecting virally‑infected cells by allowing them to escape natural killer cell‑mediated cytotoxicity...

Loss of photoreceptor cells due to retinal degeneration is one of the main causes of blindness in the developed world. Although there is currently no effective treatment, cell replacement therapy using stem-cell-derived photoreceptor cells may be a feasible future treatment option. In order to ensure safety and efficacy of this approach, robust cell isolation and purification protocols must be developed. To this end, we previously developed a biomarker panel for the isolation of mouse photoreceptor precursors from the developing mouse retina and mouse embryonic stem cell cultures...

Central nervous system (CNS) malformations play a role in all fetal malformations. Ultrasonography (US) is the best screening method for identifying fetal CNS malformations. A good echographic study depends on several factors, such as positioning, fetal mobility and growth, the volume of amniotic fluid, the position of the placenta, the maternal wall, the quality of the apparatus, and the sonographer's experience. Although US is the modality of choice for routine prenatal follow-up because of its low cost, wide availability, safety, good sensitivity, and real-time capability, magnetic resonance imaging (MRI) is promising for the morphological evaluation of fetuses that otherwise would not be appropriately evaluated using US...

Pregnancy remains a significant health risk to women in both developed and underdeveloped countries. Worldwide, 10 to 20 million women have pregnancy complications including ectopic pregnancy, preterm birth, gestational diabetes mellitus, and hypertensive states, including preeclampsia. Despite advancements in women's health research, there is a large gap in the diagnostic tools available to screen, diagnose, and monitor these conditions. Herein, we examine existing diagnostic tools, such as the human chorionic gonadotropin discriminatory zone, cervicovaginal fetal fibronectin, sFlt-1:PlGF ratio, and glucose tolerance testing...

OBJECTIVE: Prenatal ultrasound (US) screening detects the hydronephrosis (HN)-dilatation of fetal renal collecting system in 1%-5% of all pregnancies. In most children, HN is detected by prenatal US screening between 18-20 gestational week. Pelvi- ureteric junction (PUJ) stenosis is the most common etiological factor of prenatal HN and requires postnatal follow-up. Diuresis renography plays important role in the follow-up by complementing morphological information obtained by US with the data about differential renal function (DRF) and drainage...

AIMS: To evaluate the association of fetal fraction on cell-free DNA (cfDNA) testing with first trimester markers for pre-eclampsia and to investigate a possible association of low fetal fraction with increased risk for pre-eclampsia (PE) and fetal growth restriction (FGR). METHODS: This was a retrospective cohort study including all women with singleton pregnancies who had risk calculation for PE and FGR between 11+0 and 13+6 weeks' gestation and also decided to have cfDNA as a primary or secondary screening test for chromosomal abnormalities at any gestational age in two Fetal Medicine clinics in Sydney and Melbourne, Australia, between March 2013 and May 2017...

Authors of policy statements from the American College of Obstetrics and Gynecology and from the Society for Maternal-Fetal Medicine do not acknowledge the potential for their clinical income to influence their opinions, or the positions of the societies they represent. These policy statements were published in Obstetrics and Gynecology and the American Journal of Obstetrics and Gynecology, again, without acknowledgement of the potential for conflict of interest. The case of non-invasive prenatal testing, which has threatened the role of maternal-fetal medicine in the practice of prenatal screening and diagnosis, and has significantly reduced the demand for invasive prenatal diagnosis, illustrates the importance of identifying this potential conflict...

Genomic based technologies are firmly implanted into clinical medicine. They arrived rapidly and their uses continue to evolve in both the pre and postconception periods. These technologies migrated from the prenatal arena into the domain of the reproductive endocrinology and infertility specialists in some cases nearly simultaneously (expanded carrier screening), in others more slowly (chromosome microarrays), and for some technologies the ethical and cost concerns have resulted in a slower diffusion across the disciplines...
